VAG-COM

The 06 Jetta uses a series of computers for the car's multiple systems

(Engine, Electronics, Steering, Etc)

With the proper tool it's possible to monitor and adjust the settings of these computers.  I used VAG-Com to turn an old laptop PC into a sophisticated diagnostic tool which performs the same functions as the VW dealers system.

UPDATE: I am now offering Vag related services to the VW community.
Full details are available at
VagServices.dschein.com

Below is A List of the Programming Adjustments I have made to my car and here is a picture of my VAG-Com setup in action!


Warning: Do not, let me repeat this, DO NOT use these codes in your car.
Start with the codes from your car and use the Long Coding Helper to make the required (desired) changes.
You have been warned!
